1 GTC Technology Rethinking Xylenes Production via Toluene Methylation Joseph C. Gentry Director, Global Licensing IOCL Petrochemical Conclave New Delhi February 7, 2014
2 Re-thinking Xylenes Para-dimethylbenzene (PX) Intermediate for polyester manufacture Among fastest-growing petrochemicals
3 PX Manufacturing Overview of paraxylene production, with benzene by-product
4 PX Manufacturing Overview of paraxylene production, with benzene by-product Conventional processes do not address the fundamental problem of methyl group shortage
5 PX Manufacturing Overview of paraxylene production, with benzene by-product Conventional processes do not address the fundamental problem of methyl group shortage GT-TolAlk sm is the unique technical solution to maximize PX production from mixed aromatics

12 Limitation for PX from Reformate Methyl Group Shortage Aromatics derived from reformate has a shortage of methyl groups to maximize PX Typical in Reformate (wt%) Required to make PX Methyl Group Shortage Benzene 10 Two methyl group addition 2 Toluene 29 One methyl group addition 1 Ethylbenzene 6 Ethyl group converting into two methyl group 0 or 2 Mixed Xylenes 28 Purification and isomerization 0 C9+ Aromatics 12 C2+ alkyl group removal and methyl group transalkylation -0.5
13 Transalkylation Technology Transalkylation simply shifts methyl groups from one aromatic to another Toluene disproportionation (TDP) Toluene transalkylation (TA) with C gas C 2 H 5 By-product benzene is inevitable due to imbalance of methyl groups in the feed
14 Equilibrium Concentration, mol.% Yield Pattern of Toluene/A 9 /A 10 Transalkylation Equilibrium Distribution of methyl substituted aromatics TetraMB Xylenes TriMB Transalkylation rearranges the methyl groups. Toluene Benzene Reformate Feed To maximize PX, methyl groups must be added. Methyl/Phenyl ratio in Feed Goal for Xylenes = 2.0
15 Benzene Not an On-Purpose Product Benzene pricing is volatile, and sometimes low A significant portion of world benzene supply is from co-product of PX manufacture. Benzene periodically goes into oversupply due to market reasons; and is in chronic oversupply on a regional basis. TDP, STDP, and transalkylation yield by-product benzene due to deficiency of methyl groups. Benzene USD/MT
16 Need to Lower Feedstock Cost, and Optimize the Product Mix Maximize the value among benzene, toluene, mixed xylenes, PX Make petrochemicals, not fuels PX for polyester is the goal Benzene Toluene/A 9 /A 10 Paraxylene USD/MT USD/MT USD/MT Supporting price for BTX is crude oil
17 Molecule Management with New Feedstock Methyl group addition is the only way to counter the lower yield of xylenes. This is done by alkylating low-cost methanol. Benzene Toluene/A 9 /A 10 Paraxylene USD/MT USD/MT USD/MT H H C O H Methanol H USD/MT Supporting price for methanol is natural gas
18 If I were a chemist..... Conventional PX technologies utilize existing molecules. Chemists synthesize new molecules by adding individual parts. How do you integrate new methods, with traditional production techniques?
19 The Magic Number is 8 (Carbons) GT-TolAlk Only Toluene Methylation adds molecules Hydrodealkylation subtracts methyl groups Isomerization neither adds or subtracts Transalkylation shifts surplus methyl groups to other molecules, and removes ethyl groups and higher
20 Methyl Group Management Hydrodealkylation removes methyl groups to produce on-purpose benzene. By-product is fuel gas. Transalkylation and Isomerization re-arrange methyl groups and remove higher alkyl groups. Toluene Methylation adds methyl groups to produce xylenes. By-product is water. + OH + H 2 O
21 GT-TolAlk Process Scheme Simple, fixed-bed design with no hydrogen compressor or circulation Recycle Toluene Off Gas Light Ends MX to PX unit Toluene Methanol Reactor Stabilizer Separator C9+A to Transalkylation Post-fractionation Waste Water
22 Typical Condition and Yields for TM Condition Catalyst Temperature ZSM-5 based o C Pressure 3 kg/cm 2 H 2 O/HC 2/1 WHSV 4 hr-1 Toluene conversion (per pass) Methanol utilization (methyl group to aromatic ring) 86 wt%
23 Economics for GT-TolAlk Basis: 400 KTA Toluene / 2013 Raw Material and Product Prices (IHS) Feedstock KTA Unit price, $/ton Annual $MM Toluene Methanol Feed Costs $530 Products Fuel Gas Mixed Xylenes A Process Water Products Value $ 613 Utilities 38 Net Margin $ 45 TIC (USGC, 2013, reaction plus fractionation) $ 42 Simple ROI = 12 Months
24 GT-TolAlk, Drop-in to Existing Aromatics Complex Only paraxylene is produced from aromatic feed.
25 Summary Relative shortage of xylenes from traditional refinery sources; regional surplus of benzene GT-TolAlk replenishes the methyl group shortage to yield more xylenes Simple fixed-bed, low pressure process No hydrogen is needed Very low EB yield in the xylenes; debottlenecks adsorption separation systems Unique process system can convert 100% of aromatic molecules to PX with zero benzene by-product; or maximize benzene production if market justifies
26 Cutting Edge Cutting Edge Processes for PX Production CrystPX - low-cost efficient crystallization process for paraxylene production AdsorbPX - PX recovery by selective adsorption GT-Hybrid PX - Combination of adsorption plus crystallization for reliable, low-cost PX manufacture in revamps and grassroots applications GT-TolAlk - PX manufacture from lower-cost raw materials, with no benzene production GT-BTX PluS - Patented process to recover aromatics from FCC gasoline by direct extraction GT-Aromatization - Aromatics created from C4-C8 olefins, LPG, and light naphtha GT- IsomPX and GT-TransAlk - Aromatics transformation using catalysts from Clariant
